Thel 4,lamp supporting brackety of my nvi'nili-i'n allows:` the lamp 1 nnivereal adjusting nnlvninrnt with relation to the Windshieldv Said bracket consists of a horizontal arm 9 haring one end formed as a reduced threaded portion 10 extended through the ont-Side and inside reinforcing Shells l* of thev lamp easing 'l and held by a. pair of plain washers 11, a look washer 12 and a vlan-k nat 18. This allows the lamp tuming movement about a horizontal axis. The opposite end o'l the arm is enlarged as indiratwl at 14 and has a transverse hole 15 therein adapted to receive and conduct the vfeed cable 16 of the lamp therethrough. Thil food cable enters the lamp casing at a point. below the connection of the ann 9, and there provided with ay suitable rublwr or other protector 17; Below the enlargement Il! the lamp carrying alrm 9 is reduced and threaded 'and extends downwardly' a a sind portion 91 which passes throngh a hol(` lh in the outer end of an nndixing r-lainp f t-arrying arm 19, being hold In .wald arm l1 a pair of plain Wash- ;L a lofl: washer 21 and a check nut 22 ilnwa'lrd on said extension 91. The extenaina il' lla-raton` allon'eI the lamp movement ah'nl a rertioal axis.

lho opposite ond of the clam i arm 19 is fra'nwd aa a downwardly exten ing appr@ priatcly carved rast-ing const-itiiting the esl fixed jaw of the windshield clamp. The" casting 23 is slotted on each side of its connection with the arm 19, as indicated at 24-24 to receive a pair of independently -adjustable jaws 25 which are pivoted on a 4similarly disposed lugs 241 overlying the lugs 231 and through .which pass independent set screws 29, whereby to hold the adjustlnents of the jaws. v

My clamp may therefore be attached to windshield tubing of various diameters and by reason of the independence of action between the jaws, the jaws may be fitted to tubin of varying tapers as well as varying iameters. Moreover, the set screws operate against the lugs 241 of the adjustable jaws, instead of against the windshield tubing itself, so that they may be set up with any amount of pressure necessary to hold them without bearing against and flattening out the tubing. This obviates the formation of a depression in the tubing and a consequent development of a play suiiicient to permit the lamp to rattle under the vibration of the automobile.

Various modifications in the form and construction of my invention may obviously be resorted to if within the limits of the appended claims.

What Ither-efore claim and desire to secure by Letters Patent is:

l. A clamp comprising an arm having a iixed jaw, a pair of independently adjustable jaws operatively connected with said fixed jaw, and a pair of independently operable members carried by said fixed jaw and operating each against one of said movablejaws lfor independently adjusting said movablel jaws to thereby adapt the clamp to supports of varying cross section.

2. Means for connecting a lamp to supprts of various sections, comprising an arm having a. substantially vertical end wall of hook-shaped cross-section to form a seat for the support, lugs on the back of said wall, spaced hinge-like bearings at one edge of thc wall, independent clamp-leaves pivoted in said bearings, screws in said lugs for closing the leaves onl the support, and an arm pivoted on the clamp arm, and upon which the lamp is turnably mounted.

3, A clamp and hanger for lamps, comprising 'an elongated main hinge-like leaf with a concaved face forming a seat for a support to which the clamp may be attached,

one edge of the leaf having spaced bearings, a pintl therein, independent leaves on said pint-le and havingr ears projecting rearwardly thereof, lugs on the back of the elongated leaf, screwsI in said lugs for acting on the ears of the pivoted leaves, and an arm projecting rearwardly from the intermediate portion of the main leaf and to which a lamp is connectible for universal movement.

'4. A clamp comprising an arm terminating in a downwardly extending curved fixed jaw, a pair of spaced lugs extending rearwardly from said jaw, a pair of independently adjustable curved jaws pivoted near one end of said fixed jaw at opposite sides of said arm, a lug extending rearwardly beyond the pivot of each adjustable jaw, and overlying said pair of lugs, and a set screw engaging each pair of overlying lugs for independent-ly adjusting said pivoted jaws to supports of varying cross-section.

5. A bracket for mounting a lamp in universally adjustable relation to a support comprising offset parallel lamp and clamp carrying arms pivotally connected with each other at their voverlapping ends, al headed stud on said lamp carrying arm adapted to be fitted in a lamp, and a clamp on said .clamp carrying arm adapted to adjustably engage the tubing of the windshield to ac` commodate 'the bracket to variations in the cross-section of the tubing.

'6. A bracket for mounting a lamp in .universally adjustable relation on a .windshield comprisin a laterally disposed arm having one end isposed in the plane of. the-arm,l and reduced and threaded for swivel connection with the lamp and having its. opposite end disposed transversely to the plane of the arm and reduced and threaded for swivel connection with a windshield engaging arm, and a windshield engaging arm disposed below said lamp carrying arm and parallel thereto and carrying a windshield clamping device at its free end.

7. A bracket for mounting a lamp in universally adjustable relation on a support, comprising a lamp carrying arm adapted to be attached to a lamp at one end and having a solid perpendicular stud or projection on its other end provided with a guide opening for the reception of the feed wires of the lamp, a clamp carrying arm extending par-I allel to said lamp'carrying arm and having a clamp at one end adapted to en age the 120 support, and having its other gn formed with an opening therethrough ,for the re ception of the studorl projectidn on said lamp carrying arm. f

8. In combination with a lamp-having. aperture therein, a bracket for adjusta mounting said lamp upona s ultable sgpgrt including an arm adapted to, be operatlveiy connected to said support and havingI one end reduced and threaded `for insertion 30 through the aperture ofthe lamp; and a plain bearing element, a lock deviee, and a check nut threaded on said reduced extensioirfrom within the lamp casing and pro.

viding a joint allowing `said lamp turning movement about said arm as an axls.

9. A clamp for use upon supports of vary-v ing crossnsection and external configuration,

comprising a fixed jaw and a pair of inde- 10 pendently movable jaws pivotally connected with said fixed jaw, and means for independently adjusting said movable jaws to ,adapt the clamp to supports of varying cross section.

10. A clamp for use upon supports of varying cross section, comprising a relatively fiXed-jaw and a pair of independently movable jaws pivotally connected with said fixed jaw,` and means operating directly against said movable jaws for independently adjusting them to adapt the clamp to supports of varying cross section.

l11. A clamp for use upon supports of varying cross section', comprising a relatively'fixed jaw and a pair of independent duplicate movable jaws pivotally connected with said fixed jaw and together spanning an area substantiall equal to the area spanned by the fixed jaw, andmeans for independently adjusting said movable jaws to section. j
